A geotextile is a permeable geosynthetic material that exists between the soil and pipes, gabions or retaining walls to enhance the movement of water and hinder the movement of soil.
Filament geotextiles are made of super-strength polyester chips by spinning. It is made by air drafting, netting, pre-pressing and needle punching.
feature:
1. The physical properties are stable, and the original performance can be maintained for a long time;
2. Stable chemical properties, strong acid and alkali resistance;
3. Good water permeability;
4. High temperature resistance, freezing resistance, adapt to different external environments;
5. Light weight, can be packaged according to certain requirements, convenient for transportation, storage and construction.
The production process of filament geotextile:
This series of needle punched non-woven fabrics is formed by fine carding, multiple precision needle punching or appropriate hot rolling. Filament needle-punched non-woven fabric is to put the jet-stretched fibers into the fiber web through metal wires, and then pre-compress the fiber web by hot rollers and reinforce by needle punching. The needle is barbed, and the fiber web is repeatedly punctured. The hook tape is reinforced with fibers to form a needle-punched nonwoven.
